Which term is the part of a graph or plot that explains symbols?

• A. Label
• B. Plot
• C. Survey
• D. Key

Answer: (D)

The part of a graph that explains symbols is the key. It tells you what each shape, color, or line represents, so you can understand the data correctly—like which symbol stands for apples or oranges. A label is for naming parts or axes, not for decoding every symbol. A plot is the graph itself, the drawing of the data. A survey is a way of collecting information, not a feature of the graph. So the key is the best choice because it provides the legend that connects symbols to their meanings.
